Barrier improvements

A method of effecting a barrier comprising an upper elongate support and a lower elongate support which is parallel to the upper elongate support, and a two-wire tensioning assembly with two only substantially vertical portions extending between the upper and lower elongate supports, there being either one wire being a separate length of wire having a single length with thereby two respective ends, each end anchored at a position which is spaced apart one from the other, one end being secured directly or indirectly to a first of the elongate supports and the other end being secured to the same elongate support, one wire between its respective substantially vertical portions providing a loop portion which is inter-engaging with either a spreader which engages between the vertical portions keeping them separate, or the support oppositely positioned to the spreader, or there being two wires each being a separate length of wire with one end secured either directly or indirectly to, in each case, a one of the supports but spaced apart one from the other, and in the case of the other end in each case, with the other support either directly or indirectly, and where, by being indirectly attached, is by being attached through the spreader, the spreader in every case having a threaded aperture and a shaft threadably engaging the aperture and being positioned to either directly or indirectly engage a one of the elongate supports, the method comprising:

• effecting inter-engaging of the respective ends of the respective wires with the spreader;
• and
• rotating the shaft relative to the spreader whereby to effect an increase in tension of both substantially vertical portions of the wire at the same time.
